[PATCH 5.17 336/343] powerpc/64: Fix build failure with allyesconfig in book3s_64_entry.S

[Greg Kroah-Hartman]

From: Christophe Leroy <christophe.leroy@xxxxxxxxxx>

commit af41d2866f7d75bbb38d487f6ec7770425d70e45 upstream.

Using conditional branches between two files is hasardous,
they may get linked too far from each other.

  arch/powerpc/kvm/book3s_64_entry.o:(.text+0x3ec): relocation truncated
  to fit: R_PPC64_REL14 (stub) against symbol `system_reset_common'
  defined in .text section in arch/powerpc/kernel/head_64.o

Reorganise the code to use non conditional branches.

Fixes: 89d35b239101 ("KVM: PPC: Book3S HV P9: Implement the rest of the P9 path in C")
